Hi,

I have a script which plots a histogram, and I have set it so that there is a main xtick every 50. I would like to also have minor ticks every 10, in addition, I want the minor ticks to be unlabelled also and pointing outside the graph. Help on this would be much appreciated. Thanks.

    p = Length; 
    xbins=0.5:1:200.5;
    [j,qout] = hist(p,xbins); %Use 30 bins for the histogram
    bar(qout,j/sum(j),'k'); %relative frequency is n/sum(n)
    xlim([0 200]);
    ylim([0 0.025]);
    set(gca,'xtick', [0:50:200],'FontSize',15); 
    set(gca,'XMinorTick','on','YMinorTick','on')

EDIT: I have put

set(gca,'XMinorTick','on','YMinorTick','on')

In the code, but I still don't know how to set those ticks pointing outwards and to have a set no. of them.

在 MATLAB Online 中打开

http://www.mathworks.com/help/matlab/ref/axes-properties.html#property_tickdir

set(gca, 'TickDir', 'out')

As of R2015b there is also a per-axes control of this; see http://www.mathworks.com/help/matlab/ref/numericruler-properties.html

Hey Walter, this answer worked fine. Though is there a way to only have them on the two axes? rather than all 4 sides of the graph?

With HG2 (R2015b and later) TMW finally gave such fine detail control...see <Numericruler Properties>. Look for MinorTick, MinorTickValues properties. The direction is set via 'TickDirection' and affects both sets.

If you have an earlier release, the minor ticks are automagically adjusted based on the tick spacing and are not otherwise controllable other than 'on|off'
